Lenovo Stack Review: Modular Gadgets For Road Warriors


Below, you'll see results from a handful of standard disc drive tests. The long and short of it is this: the 2.5-inch HDD within the ThinkPad Stack puts up read/write speeds in the neighborhood of 115MB/sec under normal circumstances.

ATTO Disk Benchmark
More Information Here: http://bit.ly/butV6w

ATTO is a "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure bandwidth, rather than I/O response time, access latency, etc.

HD Tune v5.50

EFD Software's HD Tune is described on the company's web site as such: "HD Tune is a hard disk utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more." The latest version of the benchmark added temperature statistics and improved support for SSDs, among a few other updates and fixes.

CrystalDiskMark Benchmarks
Synthetic File Transfer Tests

CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides a quick look at best and worst case scenarios with regard to drive performance, best case being larger sequential transfers and worse case being small, random transfers.

Wireless Performance 
Wi-Fi Router Testing

In our testing, the Stack's Wi-Fi router performed admirably, particularly for such a small device. Granted, the range is much less than a larger MIMO unit with multiple antennas, but remember: this router is designed to be used in close proximity to a mobile workstation, so range should be less of a concern.


In a file transfer test, which shuttles a ~2GB file to a network drive, we saw transfer speeds range between 2MB/sec and 3.5MB/sec, with the average being around 2.8MB/sec. It took around 10.5 minutes for the entire file to transfer over to the 2.5-inch HDD in the ThinkPad Stack.
